Local Hero (person)

A local hero is a guy (or girl) who is considered to be legendary in the neighborhood where he lives. Its a dude who there is tons of rumors about, mostly rumors about his great or stupid deeds. The rumors are earned either by always doing good things for the community or by exsessive stupidity or incredible coolness. The local hero is mostly loved by his surrounding community. A local hero is not often a hero in the real sense of the word, rather considered to be a loser by everybody who doesn´t know that he is the local hero.
